You can hover over the switch pins to see their Terminal labels. Why do we need a resistor in order to read the switch?Īt rest, the two sides of this switch are not connected to one another. Wire up the LED anode (positive, longer leg) to Arduino pin 13.ĭrag a pushbutton from the components panel to the center of your breadboard, and place it across the center column break so that its legs are plugged into four different breadboard rows.Ĭlick to create a wire connecting one button leg to power.Ĭonnect the diagonally opposite leg to Arduino digital pin 2.Ĭreate and position a high value resistor (such as 10K) between that same button leg and ground. The resistor can go in either orientation because resistors aren't polarized, unlike LEDs, which must be connected in a certain way to function. Plug the LED into two different breadboard rows so that the cathode (negative, shorter leg) connects to one leg of a resistor (anywhere from 100-1K ohms is fine). Identify the pushbutton, LED, two resistors, and wires connected to the Arduino in the Tinkercad Circuits workplane.ĭrag an Arduino Uno and breadboard from the components panel to the workplane.Ĭonnect breadboard power (+) and ground (-) rails to Arduino 5V and ground (GND), respectively, by clicking to create wires.Įxtend power and ground rails to their respective buses on the opposite edge of the breadboard by creating a red wire between both power buses and a black wire between both ground buses. You could load up a new Tinkercad Circuits window and build your own version of this circuit along side the sample. Remember that the breadboard rows are connected inside, so you can plug in components and wires to make quick temporaryĬonnections. It's perfect for learning, teaching, and prototyping.Įxplore the sample circuit embedded here by starting the simulation and testing the pushbutton.

Tinkercad Circuits is a free browser-based program that lets you build and simulate circuits. You can even view this lesson from within Tinkercad (free login required)! Explore the sample circuit and build your own right next to it. You can follow along virtually using Tinkercad Circuits. To optionally build the physical circuit, gather up your Arduino Uno board, USB cable, solderless breadboard, an LED, resistors (one from 100-1K ohms and one 10K ohm), pushbutton, and breadboard wires. A pushbutton is one kind of switch, a mechanical device that connects or breaks a circuit. Your Arduino board can be programmed to listen to electrical signals and take actions based on those inputs. This lesson builds on outputs by adding an input. So far you've learned to control LEDs with code, which is one use for Arduino's outputs.

Let's learn how to read a pushbutton using Arduino's digital input! We'll connect up a simple circuit using a solderless breadboard and use some simple Arduino code to control a single LED.
